Anyone here built a GyroBee?

Hi guys.

I have this old dream af building a gyroplane - a GyroBee, specifically.

And I have all the expensive parts, I just need to get some aluminum.

But I need drawings of a rotor head for the McCutchen Skywheels rotor blades
and a kick in the butt to get me started - it's already taken 25 years.

The last few years I've had both lathe and mill plus I know a certified alu welder,
so I really have the means to build it.

Cheers
Erik
